  1 - Nonlinear Fuzzy Volterra Integro-differential Equation of N-th Order: Analytic Solution and Existence and Uniqueness of Solution
  L. Hooshangian
  This paper focuses on the fuzzy Volterra integro-differential equation of nth order of the second-kind with nonlinear fuzzy kernel and initial values. The derived integral equations are solvable, the solutions of which are unique under certain conditions. The existence أکثر

  This paper focuses on the fuzzy Volterra integro-differential equation of nth order of the second-kind with nonlinear fuzzy kernel and initial values. The derived integral equations are solvable, the solutions of which are unique under certain conditions. The existence and uniqueness of the solutions are investigated in a theorem and an upper boundary is found for solutions. Comparison of the exact and approximated solutions shows the least error. تفاصيل المقالة

  The convergence of thisiterative sequence is then controlled by an embedded parameter. The fastest convergence occurs for an optimal embedded parameter which maximizes a special function. This optimization problem brings a sequence with high rate of the convergence to t أکثر

  The convergence of thisiterative sequence is then controlled by an embedded parameter. The fastest convergence occurs for an optimal embedded parameter which maximizes a special function. This optimization problem brings a sequence with high rate of the convergence to theunique solution in the finite region where $\frac{\partial f}{\partial y}$ has to be positive.Some illustrative examples are given to confirm the validity and reliability of this constructive theory. تفاصيل المقالة

  4 - An Extension of Mixed Monotone Mapping to Tripled Fixed Point Theorem in Fuzzy Metric Spaces

  In this paper, we prove the concept of fuzzy metric spaces of tripled fixed point via mixed monotone mappings and prove the existence and uniqueness theorem for contractive type mapping. In order to do that, we consider a modification to results on tripled fixed point t أکثر

  In this paper, we prove the concept of fuzzy metric spaces of tripled fixed point via mixed monotone mappings and prove the existence and uniqueness theorem for contractive type mapping. In order to do that, we consider a modification to results on tripled fixed point theorem in fuzzy metric spaces available in literature. Additionally, we prove some tripled fixed point theorems for metric spaces via mixed monotone mappings. These results extend and generalize some recent results in literature. تفاصيل المقالة
